You were like many of my best students. They love the complicated hard stuff! Relativity and Quantum p Physics are always fun because they really require us to stretch our brains beyond our everyday experience. I also do sections on acoustics and light and colors, many of the Liberal Arts students really love these sections. Just know to you Diana. You do an excellent job! Physics Girl rocks!
Fantastic video! I only wish I could understand it! You make physics simple, and yet at the same time you remind me why I dropped out of physics in high school. At 47 yrs old, I've missed my opportunity to be a scientist, but I feel, based on your videos, that if I had a tutor with your knowledge at the time, my education and subsequent career would have been vastly different from what it is today. Your videos are very inspiring and I hope that millions of young people are watching and using the knowledge that you impart to further enhance their lives. You are doing a great service to your fellow humans. Be proud of that and continue on inspiring young scientists. I know this probably flies in the face of everything you believe, but I thank God that you exist and you are helping to spread knowledge and understanding to a new generation. Sincerely.
_For my ally is gravity, and a powerful ally it is. Planets creates it, makes them grow. Its energy surrounds us and binds us together. You must feel gravity around you; here, between you, me, the tree, the rock, everywhere, yes. Even between the land and the ship._
You, dear miss, are exquisitely, wonderfully, objectively awesome. Thank you for helping to create, and being the face of, such amazing content. You give me hope for future generations, and hope you continue to teach for many years to come. Thank you. Thank you. Thank you.
Great stuff. And THANK YOU SO MUCH for such an understanding and approachable presentation of what centrifugal force is in a physics classroom. (I am campaigning for physics teachers to stop saying, "There is no centrifugal force." You explained it exactly the right way.)
Here you go, ua-cam.com/video/NH1_sO8QY3o/v-deo.html This is Khan Academy video where Salman Khan explains and derives the formula for Centripetal Acceleration just by intuition, this is the excellent explaination, you will really learn a lot from this video,
love this vid sooo much. did calc 2 and dif-eq back many years ago, but since my masters is neuroscience, i've forgotten a lot of it by now. love the refresher course
Dianna I just love going to school with you as teacher. You just explained the road ?. Some of the rest I know. But nobody ever has explained the force of the different road grades. Thanks Dianna
I appreciate you addressing the "oh so controversial" centrifugal force. Like many, it was taught to me as just fictitious but yes... things are not so straightforward.
Love these vid! They are helping me with my senior ap physics c class so much! Especially with school being online this year I need all the help I can get, keep it up!
I really enjoy and learn much from your explanation Please never stop making such awesome videos. Physics is all so exciting when we have teachers like you.
Keep in mind, we're just looking at galaxies and haven't seen them spin at all except for at the centers (such as Sag-A* time lapse and remote BH imaging effects). We've just seen some redshift/blueshift elsewhere on larger galactic scales -- nothing else. It's possible that galactic centers are actually hurling material waves outward like pinwheels, which generate periodic star bursts that tend to maintain their original velocity from ejection. They would also be slightly spun up by tidal interactions. Incidentally, the laser-measured tidal recession of our own moon closely matches the expansion of space time estimated on much larger scales (it's in the same ballpark, anyway). With the never-ending, massive failures of big bang, alternatives are in play.
Thank you for correctly calling the INWARD force centripetal. In the past few years this universally accepted mistake has popped up in the internet: People call the outside force centripetal force. I mean, the clue is in the name. Centri -> center ; fugere -> fleeing => Fleeing the middle.
Nice shout out for Ringworld. 👍👍 Awesome series BTW. Your presentation is the style I wish everyone could experience in formal school. It's makes what could be a dry, boring subject interesting. I remember my first physics lessons. On TV (remember that archaic device?) with Prof. Julius Sumner Miller. To me, a geek, it was the most interesting part of a little Canadian TV show (now with a huge cult following) called The Hilarious House of Frightenstein (starring, among a couple of others, Billy Van and Vincent Price).
Always eagerly waiting for her remarkable shows, full of knowledge & curiosity... Please do one more thing- Do upload subtitles from your end for these presentations, bcz most of the young population (who need it most) of Non-western countries are unable to get this precious information bcz of fear of not understanding spoken English very well..
AWESOMENESS IS THE WORD THAT IS INCREDIBLY SMALL FROM WHAT YOU REALLY DO, AND YOUR GENEROUS TEAM. THANKS FOR YOUR OUTSTANDING CONTENT, VIRTUAL HIGH 5 ✋✋👍👍
Thank you for this..My husband is one of these guys...I remember when this was a new trick ..and now I can share your video with our 13 year old youngest daughter for homeschool! So fun to find this!
Dianna you should really watch (or read) the expanse if you want to see what the future could look like! They have a spaceship that imitates 0.3 earths gravity by spinning a big drum in the middle and every spaceship does a "flip and burn" to get some resemblance of gravity! It's awesome
First thoughts about the motion of going in a circle and speeding up made me think of Furze's large donut where he rode around on the wall. Then you talk about bent space and I remembered that Veritasium did his video on that a few days ago. Great how all of UA-cam relates back to itself. :)
@7:34 A CORRECTION IS NEEDED. YOU do not feel the centrifugal force when you are in the spinning ride. YOU feel the centripetal force of the wall pushing you toward the center, which is the ACTION FORCE. The wall of the ride feels the centrifugal force from you, which is the REACTION force. I'm willing to throw down over it. Come at me bro!!!! Seriously though, she did state that incorrectly.
Mam please cover entire mechanics,thermodynamics,shm,waves, electricity and magnetism and modern physics. This is the syllabus for jee mains and only you can make it very easy 😊. Love from India 💙💙💙
Even my native language is not english i got max. Of the teaching which i dont understand from my native teachers.Loved so much . Love from India❤️. Thx mam.
Oh, and the Shaolin “Rope Dart” is based on the principle of establishing a velocity in a dagger on the end of a rope, then decreasing the radius the dagger is swinging on in order to give the dagger more force when it’s released from its circular path (on the tangent of course). I’ve always thought that decreasing the radius made the dagger move faster, but now I see the dagger actually moves slower along its smaller radius, not just as fast in a tighter circle; it just completes more rotations per minute than before. I’m now trying to figure out why that would give it a higher velocity upon release O_O! So damn cool!!!
".... boundary conditions. I'll call this the Extreme Behavior Method of Sanity Checks." I think I've always felt physics and psych have parallels. Centriptetal vs. Cetrifugal (aka objectivity), behavioral inertia, gravity, calculating forces... this one's a gold mine!
The radius of the round corner is needed in Problem 3 in order to calculate the answer. But it will be a bit of work for AP or IB. Thanks anyway. Good lesson.
Professor you are amazing! And a little spooky, you always post a video on the exact issue I am struggling with. You do a terrific job at explaining it so I can understand it better, but I'll have to remember not to drink coffee before watching-because you inject enough energy into the experience that it takes hours for my brain to slow down. Thank you very much!!
Have you ever considered writing a basic physics book? With references to your UA-cam videos? You have a talent for presenting things in a way that make sense.
Hello Physics Girl Dianna. Like your vids however, I have a question for you and I realize I am changing gears on you: Compare Mars and Earth: Average Global Temp of Mars is -87F. 95% CO2 in Mars atmosphere and 1% Water Vapor. Average Global Temp of Earth is 59F. .04% CO2 in Earth's atmosphere and 4% Water Vapor. Mars atmosphere is about 1% that of Earth. Mars gets about 60% of the solar heat flux compared to Earth in watts/meter squared. The CO2 concentration is about 2,400 times that of Earth, while water vapor is 0.25 times that of Earth. Earth's atmospheric pressure is about 167 times that of Mars. Normalizing CO2 and Water Vapor in the Mars atmosphere using the pressure factor gives for CO2: 2,400 / 167 =14.3 and for Water Vapor: 25 / 167 =.0015 Taking the 60% factor for the solar radiant heat flux gives: 8.6 for CO2 and .009 for Water Vapor. If my assumptions are are not too far fetched, the relative heat trapping effectiveness for Mars' when directly compared to Earth shows that Mars has 8.6 times the CO2 heat trapping ability of Earth, but only .0015 times the Water Vapor heat trapping ability. The conclusion drawn is that CO2 is insignificant for trapping atmospheric heat radiated from the surface. However, Water Vapor is extremely important for trapping atmospheric heat radiated from the surface. BTW, if CO2 is so important why am I heating for 9 months for the last 2 years whereas 10 years ago I only had to heat for 7 months.
One of the things that turned me off of physics in high school were all the formulae for force. Chap 1, Pg 1, "What is Force". "Force is mass times acceleration." F=ma. But then F=(mv^2)/r, F= -kx, F=(Gm1m2)/r^2, ... Every time I turned around, there was a new formula for F. I have since reconciled myself to what's going on, (Thank you Prof. Goodstein and the Mechanical Universe) but perhaps you can make a video of why there are so many.
Uhhh.It was damn good.Thank you for clearing my doubts.Honestly, speaking this is the way physics should be taught.Even your smiling face gives me more confident than my teachers lecture.☺
Hey, I might be wrong about this, but I think there’s an issue with the idea of using centripetal force to simulate gravity! Since centripetal force would require that everyone be contacting some portion of the spinning cylinder or at least be in contact with something that is; if someone were to accidentally stop contacting the ground, especially while moving opposite the direction the cylinder is spinning, wouldn’t their experience be that of hurtling through the air at 0G while the rest of the world moved past them experiencing their simulated gravity like normal? My reasoning is that unlike density driven gravity, in which things are pulled by a current of space-time (they’re connected to space-time like a swimmer to water, and the water is being pulled on); centripetal gravity seems to be escapable by simply disconnecting from the cylinder at an angle and velocity that counteract the tendency to travel tangent to the curve (which would have you landing on the floor again as if in density driven gravity) Let me know what you think! By the way, I LOVE YOUR SHOW!!!! I’m learning so much!! Thank you!
The Larry Niven series of Ringworld books are amazing. He writes awesome scifi with real physics in them. Not only that but he was 1 of the consultants for Ronnie Rayguns SDI (Star Wars) program.

Hello Physics Girl Dianna. Like your vids however, I have a question for you and I realize I am changing gears on you:
Compare Mars and Earth:
Average Global Temp of Mars is -87F.
95% CO2 in Mars atmosphere and 1% Water Vapor.
Average Global Temp of Earth is 59F.
.04% CO2 in Earth's atmosphere and 4% Water Vapor.
Mars atmosphere is about 1% that of Earth.
Mars gets about 60% of the solar heat flux compared to Earth in watts/meter squared.
The CO2 concentration is about 2,400 times that of Earth, while water vapor is 0.25 times that of Earth.
Earth's atmospheric pressure is about 167 times that of Mars.
Normalizing CO2 and Water Vapor in the Mars atmosphere using the pressure factor gives
for CO2: 2,400 / 167 =14.3 and for Water Vapor: 25 / 167 =.0015
Taking the 60% factor for the solar radiant heat flux gives: 8.6 for CO2 and .009 for Water Vapor.
If my assumptions are are not too far fetched, the relative heat trapping effectiveness for Mars' when directly compared to Earth shows that Mars has 8.6 times the CO2 heat trapping ability of Earth, but only .0015 times the Water Vapor heat trapping ability. The conclusion drawn is that CO2 is insignificant for trapping atmospheric heat radiated from the surface. However, Water Vapor is extremely important for trapping atmospheric heat radiated from the surface.
BTW, if CO2 is so important why am I heating for 9 months for the last 2 years whereas 10 years ago I only had to heat for 7 months.

Please fix the focus on these. The last two in particular have had blurry Dianna and tack-sharp backgrounds. For most of these shots, the focus doesn't need to change, so you can just manually focus on Dianna, and avoid letting autofocus pick the wrong target.
I love learning about circular motion with Diana :-D
I like the way of the explanations, but it goes a bit fast for me.
